Lt. Kevin Adam of the Department of Inland Fisheries and Wildlife said Saturday that wardens will continue to search for James Russell, 51, from the water and the air as weather permits. Anything unusual will be checked out, he said.

Sonar equipment, which was used Friday, will be used again this week as wardens continue to focus on a specific area where they believe Russell’s body could be, according to Adam.

Volunteers and Russell’s family members also continue to search the shoreline for Russell, who was last seen Sunday, Nov. 14, on Sand Bar Way.

Wardens believe Russell kayaked across the lake to Kineo before he went missing. His kayak and backpack were found Wednesday floating off Murray Road two miles from Kineo.

“I think somewhere on that trip something bad happened to him,” Adam said earlier this week.

Russell has made no calls on his cell phone since his disappearance, he added Saturday.

On Friday, the shoreline and trails on the west side of Moosehead Lake and the east side from Kineo to where the kayak was located were among the areas searched, according to Deborah Turcotte, spokeswoman for the Department of Inland Fisheries and Wildlife.
